Solving Two-Step Equations

Front

What is a two-step equation?

Back

A two-step equation is an algebraic equation that requires two operations to solve for the variable.

Front

What is the first step to solve the equation -6x + 1 = -11?

Back

Subtract 1 from both sides to isolate the term with the variable.

Front

What is the second step to solve the equation -6x + 1 = -11 after isolating the variable term?

Back

Divide both sides by -6 to solve for x.

Front

How do you check if your solution to an equation is correct?

Back

Substitute the solution back into the original equation to see if both sides are equal.

Front

What does it mean to isolate the variable in an equation?

Back

Isolating the variable means to get the variable alone on one side of the equation.

Front

Solve for x: -4x + 1 = 21

Back

x = -5.

Front

What is the solution to the equation 8 - 2x = 30?

Back

x = -11.

Front

What is the first step to solve the equation -5 - 6a = -59?

Back

Add 5 to both sides to isolate the term with the variable.

Front

What is the solution to the equation 9 = 4g + 13?

Back

g = -1.

Front

What operation would you perform to both sides of the equation to eliminate a constant term?

Back

You would add or subtract the constant term from both sides.
